The United Kingdom's experience of controlled donation after circulatory death direct procurement of lungs with concomitant abdominal normothermic regional perfusion with an analysis of short-term outcomes
Abstract
Background: Abdominal Normothermic Regional Perfusion (A-NRP) improves outcomes for transplanted abdominal organs from Donation after Circulatory Death (DCD) donors. Concerns have been raised about the effect of A-NRP on lungs procured during multi-organ donation. We present the UK experience of performing direct procurement (DRP) of lungs from DCD donors with A-NRP.
Methods: Retrospective analysis of all 487 UK DCD lung donors between April 1, 2011 and December 31, 2023. Organ transplantation rate and 30-day, 90-day and 1-year survival rates were compared between DRP of DCD lungs, DRP of DCD lungs with A-NRP and donation after brainstem death (DBD) lungs. Primary graft dysfunction (PGD) rates were compared between DCD lungs with and without A-NRP.
Results: Three hundred ninety-seven DCD donors resulted in a lung transplant (22 retrieved by DRP with A-NRP). There was no difference in lung transplantation rates between DRP and DRP with A-NRP. Of the 390 first adult-only lung transplants performed from DCD donors, there was no significant difference in 30-day, 90-day and 1-year survival between DRP of DCD lungs and DRP with A-NRP. There was a significant difference in survival between standard DCD donors and DBD donors at 30-days and 90-days, but not 1 year. There was no significant difference in grade 3 PGD rates at 72 hours post-implantation for DCD lungs with or without A-NRP.
Conclusion: In the UK experience, use of A-NRP is not detrimental to procurement of DCD lungs. We advocate the use of this technique until further studies can explore the safety and efficacy of thoraco-abdominal NRP for lungs in multi-organ retrieval.
